Publication number: 20240087372Abstract: A wheel state obtaining system configured to obtain a wheel state that is a state of at least one of a plurality of wheels of a vehicle includes: a wheel speed detection device configured to detect a wheel speed of each of the plurality of wheels; a traveling state detection device configured to detect a traveling state of the vehicle; and a controller. When the traveling state of the vehicle detected by the traveling state detection device is a predetermined set state, the controller obtains a wheel speed difference of two of the plurality of wheels based on the wheel speeds of the plurality of wheels detected by the wheel speed detection device. The controller determines whether at least one of the two wheels is in an abnormal state based on the wheel speed difference.Type: ApplicationFiled: June 14, 2023Publication date: March 14, 2024Applicant: Toyota Jidosha Kabushiki KaishaInventors: Yosuke KIMURA, Yoshihisa Yamada

Patent number: 8315534Abstract: Stored DC power is supplied to a load after a return to a normal-power mode or a power-up of an image forming device. An auxiliary power supply does not supply the stored DC power to the load, and a main power supply supplies AC and DC power to the load if it is determined that a predetermined processing is performed upon a starting of the image forming device. The auxiliary power supply supplies the stored DC power to the load, it is determined whether a predetermined time has elapsed, and the main power supply does not supply the AC and DC power to the load if it is determined that the predetermined processing is not performed upon the starting of the image forming device. A decision whether the predetermined processing is performed is based on at least one of a number of sheets, an elapsed time, and an environmental temperature.Type: GrantFiled: October 31, 2006Date of Patent: November 20, 2012Assignee: Ricoh Company, Ltd.Inventors: Tetsuya Yano, Toshitaka Semma, Yoshihisa Kimura, Norio Muraishi, Naoki Sato, Kazuhito Kishi
